You can insert user objects such as holding, refuelling or AWACS orbits, CAPs, SEAD CAPs, or reference points. Create flight routes by snapping way-points to airfields, nav points, reference points or orbit anchors. Move multiple overlaid objects together. Clone flights and/or organise them into packages. Navigational data are automatically calculated using an atmospheric model. Use advanced tools, such as inter-visibility plot or terrain and slope visualisation. Mark important areas by polygons, circles or labels. Export as a DCS .miz file.
One little feature that really stood out for me was the ability to set-up your countermeasures for the F/A-18C. You have to manually do this every time you fly but with CombatFlite you can do all that in the planning process which really makes a big difference in the start up process of the jet.
